Power solution manufacturer Powerocks today announced Tarot -- a backup battery designed to fit in a wallet, pocket, or small purse to provide an emergency charge for smartphones, tablets and other mobile devices quickly and safely when away from a power source or outlet. Tarot weighs 1.79 ounces, with measurements of 3.5 inches in length, 2.1 inches wide, and a height of 0.28 inches.

The battery holds a 1500mAh capacity, giving most smartphones one emergency charge. A micro USB cable is included to charge most devices, but existing charging cables such as the Apple 30-pin USB dock cable or a Lightning cable may be plugged into the device. When discharged, the device has a micro-USB input for power either from a computer or other USB power source.
